CAR-couPlume.

SPECIFICATION forming part of Letters Patent No. 396,201, dated January15, 1889.

Application filed September 21, 1888. Serial No. 286,044. (No model.)

To all whom t may con/cern.'

13e it known that we, JOHN \V. FOREST, of Thayer, Neosho county, Kansas,and SAMUEL H. SCOTT, both citizens of the United States, the latterresiding at Ohanute, in the county ot' Neosho and State of Kansas, haveinvented a new and useful Improvement in Oar-Ocupling's, of which thefollowing' is a specification.

The invention relates to improvements in car-couplers; and it consistsin the construction and novel combination of parts, hereinafterdescribed,illustrated in the drawing's, and pointed out in the claimshereto appended.

In the drawings, Figure l is a perspective view ot' the end of a carwith a draw-head embodying the invention attached. Fig'. 2 is a centralhorizontal section of two of such draw-heads coupled together, with thechains secured at their inner ends to the locking'- blocks. Fig. 3 is aperspective view of one ot' the locking-blocks detached. Fig'. 4 isadetail view ot' the face of the projection of one of the draw-heads toshow the seat therein of one ot' the locking-blocks.

Referring to the drawings by letter, A designates a draw-head suitablysecured to the adjacent end of a car and provided with the recess B,into which the projection ct'of the opposite draw-head enters, whichprojection is rounded at its end, as shown. The said recess is providedwith the roof or web l), and with the outwardly-curved directing arm orplate b to guide the rounded end of the projection a of the oppositedraw-head into the recess B, the roof or web b of which rides over thisprojection a. The said projection is provided with the transversehorizontal opening O, having the outer rectangular portion, c, and theinner portion, c', T- shaped in cross-section.

D is a recess in the inner surface of the projection a, having its frontand rear sides, d d', respectively inclined and converging inward oneach side of the opening O, which forms a seat for the correspondinglocking-block, E. The said locking-block has the rectangular shank eseated in the opening C, and is provided on its inner side and end withthe opposite flanges or studs c e', seated in the upper and lowerextensions of the inner T-shaped portions, c', of said opening. Theinner end of the locking-block is beveled outwardly at e2, and it has onits inner side a shoulder, e3, formed by notchiug said edge, whichshoulder can catch over the side oi' the outer orice of the opening O,when the locking-block is drawn outward and prevents the latter frombeing moved inward into coupling position. The end of the projection ais provided with atransverse recess and upper and lower coupling-pinholes to couple with the common link 6o and pin.

F is a strong' spring-bar having' one end secured to the outer side ot'the projection ct and the other end passed throi'lg'h a loop or staple,

f, on the outer end of the corresponding locking-block, and G is a chainhaving' the coiled spring g secured between its outer and innersections. The inner end of said chain is secured to the staplef and itsouter end to a crank-arm at the Vlower end, 71., of the rod H, 7o

j ournaled in bearings secured at proper points to the end of the carand provided thereabove with the actuating handle or wheel It. The saidcoiled springA makes the chain elastic, and

thereby prevents breakage when the chain is under tension.

The action of the coupler is as vfollows: Then the draw-heads cometogether, the beveled ends of the locking-blocks will ride over eachother in the recess l) and their rear surfaces 8o will catch' againsteach other, the locking'- blocks being forced inward by the springs F.The said blocks are unlocked by pulling' on the chains G, either at thesides of the car or from the top by means of the rod H and the wheel l.The combination of the draw-heads, each having' a recess, B, and aprojection, CL, the projection a being provided with a transverseopening having' a rectangular portion, c, and

a T-shaped portion, c', and the locking-block having a rectangularportion fitting in the loo The flanges 9o portion c of the opening, andthe flanges e', ourown we have hereto affixed om' signatures fitting nthe T-Sllaped port-ion thereof, as in presence of two Witnesses.Specified. T f
